GOLF CLUB.

Application filed February 19, 1923. Serial No. 619,961.

To all whom it may concern:

Be it known that I, GEORGE W. MATTERN,

a citizen of the United States, residing at Dayton, in the county of Montgomery and have invented certain new which the following is a specification.

My invention relatesto golf clubs and more particularly to a form of handle shaft 0 connection and the method of applying handle shafts, particularly those of the metallic tubular type to metallic golf club heads having the standard or customary form of hosel.

' The usual form of tubular metallic handle shafts which have recently come into use are uniformly tapered throughout and at the head engaging end are consequently of much smaller diameter than the socket within the To the contrary the 4 usual form of wood handle shaft is-p-rovided with a swell, or enlargement adjacent to its point of connection with the head, from which swell or enlargement projects the B tenon of such size as to completely fill the standard hosel. a,

Since the advent of the metallic handle shaft many players who possess favorite clubs of proven adaptabllity and characterdesire to have the original wooden handle shaft of such club, replaced with a metallic shaft. The present invention affords a constructionand method of adapting the golf club heads having standard enlarged 55 hosels, intended for reception of wooden handle shafts to the'smaller and uniformly tapered metallic shafts without causing the adaptation to appear cumbersome or unshapely present construction from the, view point of the manufacturer is due to the fact that it enables one type of club head hosel to be readil adapted to either wooden or metallic andle shafts, thereby eliminating the necessity for specialdies for the manufacture ofhosels of diflerent' form and the necessity of carrying large quantities of and without materially changing the 40 wei ht and balance of the club. In refitting heads having different forms of hosels in stock. v

The invention involves the use within the standard form of tapered or conical hosel of an insert bushing which conforms exteriorly to the interior of the hosel socket, and interiorly tothe tenon portion or head engaging extremity of the metallic handle shaft. This bushing is inserted within the hosel and the handle shaft in turn inserted within the bushing. In the event that the bushing insert is of metallic ,character, the parts may be integrally united by brazing Welding or other similar means, while if the insert is of other material, the parts are united by cementing or by pinning. After assembly the larger end of the hosel and the bushing which preferably, though not necessarily projects beyond the extremity of the hosel are peripherally reduced into an upwardly tapering or converging form wherein the surface of thehoselmerges uniformly with that of the bushing. The result is a rigid and durable connection of maximum strength, but of neat and pleasing appearance of double tapered form affording a medial swell or enlargement of the hosel. The object of the invention is to afiford an improved adapter and method of applying handle shafts to standard golf heads hosels,

whereby the connection will be durable of maximum strength and eiiicie'ncy and-unlikely to get out of repair.

A further object of the invention is to provide a mode ofoperation for economically and efliciently applying uniformly tapered metallic shafts to the standard golf head hosel adapted for reception ofwooden handle shafts.

With the above primary and other incidental objects in view as will more fully appear in thecspecification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation or their equivalents as hereinafter described and .set forth in the claims.

Referring to the drawings, Fig. 1 is a side elevation of a completed golf'club, having the old type of head and hosel to which the metallic shaft has been adapted by the means and method hereinafter described,

tapered form 8 conver ing upwardly point ofintersection with the handle shaft d Fig. 2 is a sectional view showing the original relative proportions of the parts.

Fig. 3 is a further sectional view of the parts in assembled relation and reduced to ultimate form.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawing wherein is shown the preferred, but obviously not necessarily the only form of embodiment of the invention, 1 is the golf club head of a mashie, mid-iron or niblick type, from which extends the integral conical hosel 2. The hosel 2 illustrated in the drawings is of the standard type, adapted for the receptionof a wooden handle shaft. This hosel 2 is 'ex-. panded upwardly so that it is somewhat larger in diameter at its extremity or mouth than at its juncture with the blade 1. In applying a wooden handle shaft to such hosel, the tenon of the shaft would conform to the socket of the hosel 2, and the shaft would be contracted or reduced somewhat beyond the end of the hosel to the desired diameter of the handle shaft. The metallic tubular handle shaft 3, as employed at the present time, is of uniform'taper and does not possess the terminal enlargement or swell possessed by the wooden handle shaft and consequently such metallic handle shaft 3 will not conform to nor fit the socket of the standard hosel. To adapt such reduced metallic shaft to the enlarged hosel, there is employed an insert bushing 4:, exteriorly tapered to agree with the interior of the hosel socket and having an axial tapered bore 5, with which the metallic tubular handle shaft 3 agrees. The bushing 4. is inserted within the hosel and the handle shaft 3 .is inturn inserted within the tapered bore of the bushing and such parts are fixedly united one with another. The bushing 4 is preferabl of metal, brass being the usual material. 11 such case the parts are united by brazing or welding, so that the hosel, the insert bushing and the handle become integrally united. The bushing 4. preferablyv though not necessarily, extends beyond the extremity or mouth of the hosel 2. The parts having been assembled and united by suitable means as brazing or welding if all of the parts are of metal, or otherwise by cementing, pinning or analogous means, the abrupt shoulders 6 and 7 formed by the extremities .of the hosel'and bushing -res ectively are eliminated by reducing the en s of the hosel and bushing to a reverse to a 3. Such peripheral reduction causes the exto merge unily united, the hosel wall is reduced to a feather edge, at its upper end, such contour being uniformly extended thereby reducing the upper end of the bushing to a substantially feather edge at its juncture with the handle shaft 3. This produces a double tapered form between the handle shaft 3 and the blade 1 of the club, or afiords a medial swell 8 of the hosel. It has been found by experiment and comparison that the portion of the bushing l remaining after the reduction of the hosel compensates quite accurately for the variation in weight of the metallic and wooden handle shaft so that in the finished product the weight and balance of the original club is retained.

From the above description it will be apprinciple involved or sacrificing any of its advantages.

parent that there is thus provided a device While in order to comply withthe statute the invention has been described in more or less specific language, as to structural features, it is to be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprises the preferred form of several modes of putting the invention into effect and the Y invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.

Having thus described my invention, I
